This is a he shou wu that is said to be cured/prepared, but gives me severe diarrhea. Raw, or not prepared he shou wu does not have the same great function for hair and energy as the correctly prepared one (cooked with black beans). And raw or not correct cured/prepared, it would indeed give you diarrhea (which this does).
I have tested this product for several weeks now, and the diarrhea just gets worse and worse.
Not very great. I don't think it is correctly prepared.
